Improved power quality bridgeless Cuk converter fed brushless DC motor drive for air conditioning system. Keywords: Electric vehicle battery charger, DC to DC converter, Power Electronics converters Battery Charger electric vehicles An 800 Wh CC/CV charger with a current rating of 16 A is developed to charge a 48 V, 20 Ah Li-ion battery, where the battery is expected to charge in less than 2 hours. The closed-loop control of the trigger pulses of the CUK and LLC converters is responsible for the CC/CV charging of the battery and hence the reduced charging time. The LLC converter eliminates switching losses by undergoing ZVS (zero voltage switching) and allows high-frequency operation.

The presented topology operates a pulse-width modulated CUK converter in DCM (discontinuous conduction mode), which serves natural current shaping without an input ripple filter. Moreover, bypassing the switching losses presented by a half-bridge converter. Heretofore, modifications were made in DCDC converter topology to incorporate bridge-less topology to increase efficiency to eliminate current inrush issues and involve galvanic isolation. The proposed model comprises a CUK converter fed resonant LLC (Inductor Inductor Capacitor) converterbased charging solution for an e-bike battery pack, wherein the CC/CV (Constant Current/Constant Voltage) charging algorithm is implemented through the LLC converter.
